A mounting assembly is for a power pedestal including a number of electrical components. The mounting assembly includes a plurality of mounting members including a first mounting member and a second mounting member each structured to engage an elongated support member and be coupled to the elongated support member. The elongated support member has an end portion. The plurality of mounting members are cooperatively structured to enclose the end portion.

The present invention relates to a power feeding apparatus and a power feeding method for supplying electric power to a submersible pump for delivering liquefied gas, such as liquefied ammonia, liquefied natural gas (LNG), or liquid hydrogen. The power feeding apparatus includes a first electrical contact secured to the submersible pump and electrically coupled to an electric motor of the submersible pump; a second electrical contact configured to contact the first electrical contact; and a power cable electrically coupled to the second electrical contact. At least a part of the second electrical contact is located in a pump column in which the submersible pump is arranged.

A downhole cable that has a cable core with an inner jacket located about it. The inner jacket has a shell located thereabout, and a pair of strength member layers surrounds the inner shell. Interstitial spaces of the strength member layers are filled with bonding layers. One of the strength member layers is at a contra-helical lay angle to the other. An outer jacket is located about one of the strength member layers, and the outer jacket is bonded with the bonding layers.

An optical voltage sensor for measuring voltage on an underground power line or for use in other scenarios in which access to a conductor is available through a blind hole. The optical voltage sensor includes a light modulating member, such as a Pockel's crystal. A reflective, conductive member is positioned at one end of the light modulating member and another conductive member is positioned at an opposed end. A voltage capacitively coupled to the reflective conductive member induces a voltage across the light modulating member, thereby impacting the amount of modulation. A beam of light is directed through the crystal and reflected back out of the crystal, where the amount of modulating can be measured. The amount of modulation indicates a measured voltage, and can be transmitted to a monitoring station where processing can determine the status of the power grid or generate other results based on the measured voltage.
